@Thomas,
I'm dissappointed in you for that. I made a serious and concrete argument that raises real questions about the merit of the WWII economic analogy. You merely hide behind an assertion that I am impervious to argument.
There is little doubt that the massive public mobilization and spending of WWII ended the depression and its second dip which occurred in 1937. However, there is are serious questions about the merits of any analogy with our present situation.
All of the nations involved in WWII, winners and losers, suffered massive exonomic and financial collapses after WWII, except the United States and Canada . We fortunately emerged from the war physically intact, and internationally as creditor nations, despite a huge domestic public debts. We faced no international economic competition, required few imports and were (uniquely) able to reinstitute postwar economic growth under these conditions. Other nations, without these benefits, were not. Our situation today is not at all like that of 1945 in these respects.
That fact alone gives the lie to the notion that the massive spending of the war was the only or best solution to the world wide depression or that, as a solution, it didn't involve any disastrous aftereffects. The massive spending during the war itself directly led Britain to a very serious post war collapse - indeed rationing continued for several years after 1945. Despite huge extractions of money from colonies and dependent states, and notwithstanding the fact that it didn't suffer the massive destructiuon of Germany, Britain suffered two decades of economic contraction after the war as it dealt with the collapse of empire and the rebuilding of its economy.
All of this strongly suggests other factors were involved, and that the prsumed lesson that massive government spending is an unfailing path to economic recovery is itself false.
